MOT Advisory Notes: Do They Cause Failure?

Understanding MOT Advisory Notes and Their Impact on Your Vehicle's Roadworthiness

The annual MOT test is a crucial part of ensuring your vehicle is safe and legal to drive on UK roads. While the primary goal is to identify major faults that would cause an immediate failure, you might have noticed that your MOT certificate can also contain 'advisory notes'. These notes can leave many drivers feeling confused and concerned: do they mean my car has failed? What's the difference between an advisory and a failure? This article aims to demystify the MOT advisory note system, explaining exactly what they signify, why they are issued, and their implications for your vehicle's long-term health and safety.

What Exactly is an MOT Advisory Note?

An advisory note is not a failure. Instead, it's a recommendation from the MOT tester highlighting issues that are not currently serious enough to fail the test but could potentially become major faults in the near future. Think of them as early warnings, giving you the opportunity to address minor wear and tear or potential problems before they escalate and lead to a failed MOT or a breakdown. These notes are recorded on your MOT certificate and are also stored on the DVSA's (Driver and Vehicle Standards Agency) computer system.

Why are Advisory Notes Issued?

MOT testers are trained to inspect vehicles thoroughly, looking for any signs of deterioration or potential issues. They follow strict guidelines set by the DVSA. Advisory notes are typically issued for items that:

• Are showing signs of wear but are still within acceptable limits for the test.
• May affect the vehicle's performance or safety in the near future.
• Are close to the legal limit for wear or damage.
• Are not explicitly listed as failure items but are still considered a safety concern by the tester.

Common examples of advisory notes include:

• Tyres with tread depth approaching, but not below, the legal limit of 1.6mm.
• Brake pads or discs that are wearing thinly but still have sufficient material to pass the test.
• Suspension components showing slight play or wear.
• Corrosion on the vehicle structure or suspension components that is not yet at a critical level.
• Minor leaks from the engine or transmission that are not causing significant fluid loss.
• Headlights or other lights that are slightly misaligned or dim but still provide adequate illumination.
• Exhaust emissions that are higher than expected but within the allowed limits.
• Worn but still functional windscreen wiper blades.

Advisory Notes vs. Failure Items: The Key Differences

It's crucial to understand the distinction between an advisory note and a failure item. During an MOT test, your vehicle is assessed against a comprehensive list of safety and environmental standards. These standards are divided into three categories:

1. Minor: Issues that are not safety-related and do not affect the vehicle's performance. These are not recorded on the MOT certificate but the tester may mention them verbally.
2. Advisory: As discussed, these are items that need attention soon but do not cause an immediate failure.
3. Major: These are faults that directly contravene the MOT regulations and will result in an immediate failure of the test.

A vehicle will fail its MOT if it has any 'Major' defects or any 'Dangerous' defects (a more severe category of major defect that could pose a direct and immediate risk to road safety). Advisory notes, by their very nature, do not fall into these failure categories.

Do Advisory Notes Cause an MOT Failure?

No, advisory notes do not cause an MOT failure. A vehicle will only fail its MOT if it has one or more 'Major' or 'Dangerous' defects. Advisory notes are purely informational and cautionary.

However, it's a common misconception that you can ignore them. While they won't make you fail *today*, failing to address them can lead to an MOT failure in the future. For instance, a tyre with tread depth approaching the legal limit might pass the MOT with an advisory note. If that tyre wears down further before the next test, or if it develops a more serious issue like a bulge or cut, it will then become a failure item.

The Importance of Addressing Advisory Notes

Ignoring advisory notes is a false economy. Although your car has passed the MOT, these advisories highlight potential future problems. Proactive maintenance based on these notes can:

• Prevent future failures: By fixing minor issues now, you reduce the likelihood of failing your next MOT.
• Enhance safety: Many advisories relate to critical safety components like brakes and tyres. Addressing them ensures your vehicle remains safe for you, your passengers, and other road users.
• Improve reliability: Catching wear and tear early can prevent unexpected breakdowns and costly repairs down the line.
• Save money: Small, timely repairs are almost always cheaper than dealing with the consequences of neglect, such as catastrophic component failure or accidents.
• Maintain resale value: A well-maintained car with a history of proactive repairs is more attractive to potential buyers and will command a higher price.

What Happens After Receiving Advisory Notes?

Once you receive your MOT certificate with advisory notes, you are not required to fix these issues immediately to drive legally. However, it is highly recommended that you do. You have a few options:

• Get them repaired at the test centre: If the test centre offers repairs, you can often have the work done there and then. This is convenient and ensures the issues are rectified promptly.
• Take your car to your usual mechanic: You can take the advisory notes to your preferred garage and have them carry out the necessary work.
• Monitor the advisories: You can choose to monitor the issues yourself, but this carries the risk of them deteriorating further without your notice.

It's a good idea to keep a record of your MOT certificates and any repairs you have carried out, especially those related to advisory notes. This can be helpful when selling your car or for your own records.

Common Advisory Notes and What They Mean in Detail:

Let's delve a little deeper into some of the most frequent advisory notes and what they signify:

Tyres

Tread depth approaching the legal limit: The legal minimum tread depth for car tyres in the UK is 1.6mm across the central three-quarters of the tyre's width. If your tyres have tread depths between 1.6mm and 3mm, they may receive an advisory note. While still legal, this depth offers reduced grip, especially in wet conditions. It's advisable to replace them soon.

Minor damage to tyre sidewall: Small nicks or cuts on the sidewall that do not penetrate the tyre structure might be noted. Significant damage, however, would be a failure.

Brakes

Brake pads wearing thin: If brake pads are below 1.5mm thickness, they will fail. If they are between 1.5mm and 3mm, they will likely receive an advisory. Replacing them soon is recommended for optimal braking performance and safety.

Brake discs showing signs of wear: Similar to pads, discs with minor scoring or lipping might be noted as advisory. Significant wear, pitting, or warping would lead to a failure.

Slightly binding brake caliper: This could indicate the start of a problem that might worsen, potentially causing uneven braking or overheating.

Suspension and Steering

Slight play in steering rack: A small amount of movement in the steering rack that is not excessive enough to fail the test. However, increased play can affect steering precision and tyre wear.

Slightly worn suspension joints (e.g., ball joints, track rod ends): These components are critical for handling and stability. Minor wear might be noted, but significant looseness will cause a failure.

Corrosion

Minor corrosion to suspension components: Surface rust on suspension parts is common, especially in areas with salted roads. If the corrosion is not deep enough to weaken the component structurally, it will be an advisory.

Minor corrosion on the vehicle structure (e.g., wheel arches, sills): Again, if the corrosion is not compromising the structural integrity of the vehicle, it will be an advisory. However, significant corrosion that affects strength or safety is a failure item.

Exhaust System

Exhaust system showing signs of surface corrosion: This is very common. As long as the exhaust is not blowing, is securely fitted, and is not excessively corroded to the point of compromising its integrity, it will be an advisory.

Exhaust emissions slightly high but within limits: This could indicate the catalytic converter is starting to age or there's a minor issue with the engine management system. It's worth investigating if it persists.
